本文介绍了一种无创测量心输出量的方法。该方法使用自适应主动脉模型并结合股骨和颈动脉的冲量断面波形的测量结果来计算主动脉流量。我们在狗身上通过使用由充满液体的导管所记录的内部压力而得到测量结果,并将其与在上升的主动脉中测量的电磁流量相比较。我们还给出了在病人身上使用外部冲量测量所得到的 This article describes a noninvasive method of measuring cardiac output. The method calculates the aortic flow using an adaptive aortic model combined with measurements of impulse cross-sectional waveforms of the femoral and carotid arteries. We measured the results on the dog by using the internal pressure recorded by the fluid filled catheter and compared it to the electromagnetic flux measured in the ascending aorta. We also show the measurement of external impulses on the patient
